Specification of Letters Patent. l

Application filed August 26. 190'1. Serial No. 399.231.

. adapted to be readily connected to the wavzo ter-su ply pipe of ahousev and which will act as a filter and also dis ense withthe neces-4sity of a pressure regu ator, la further object being` to furnish Waterunder either high pressure or low pressure, as may be desired.

A further object is to provide easy means for clearing the filter.

The accom anying a yplan view of the filter and associated connections.Fig. 2 is an enlarged sectional view taken longitudinally through thefilter barrel; Fig.` 3 is a longitudinal section through 'a modifiedform of filter cone. Fig.

` 4 is a section on line .x4-m4 of Fig. 2.

of the barrel 1.

1 designates a filter barrel which is formed near `each end with'twointernal fian'ges, 2

and 3. Secured to each end of the barrel 1 Aby means of a union 4 is areducer 5, there' being two washers 6 arranged between the end of eachreducer 5 and the outer flange 3 Arranged within the barrel 1 is afilter cone 7 the larger end of which has a flange 8 which is clampedbetween the in- -nel' washer 6 and the adjacent flange 3 of the barrel,and the filter cone 7 is thus supported in position concentricallywithin the barrel 1. The cone 7 extends through the entire length of thebarrel and may be formed ofJ a wire screen kas shown in Fig. 2, or asshown in Fig. 3, might comprise a wax or cement cone hav- Yingperforations. A pipe 21 is connected to the reducer 5 and forms theinlet, being arranged 'to introduce water into the. end of barrel 1" atthe small end of the cone. A tee 9 is connected with the ipe 21 and abranch pipe 10 extends lateral y from the tee and then parallel with thebarrel 1. Pipe 10 has 1 atee 11, and a pipe 12 formed in two sections,

connects tee 11 with barrel 1, the two sections .of pipe 12 being joinedby a union 13,v

there belng a valve 14 in the section 12 between the union 13 and tee11. The pipe 21 adJacent the reducer 5 is provided withA a tee ytheother end of the barrel a pipe 18 leads drawings illustrate the yinvention an referring thereto z-Figure 1 is c with equal facility.

15, to which is connected a faucet 16, valve 17 being arranged betweentees 9 and 15. At

from the reducer 5 to a charco tank 19.

valve- 2O is arranged in pipe 10 beyond the tee 11.

In operation water enters through pipe 21, valve 17 being open, andvalves 14 and 20 closed. The water passes through the reducer 5 into thebarrel 1 and ercolates through the filter cone 7, the mes es of thelatter arresting the impurities which thus accumulate in the barrel 1.The water after passin through the meshes of the filter cone 7 and eingpurified, asses into the reducer 5 at the large end o ,the cone andthence through pipe 18 into tank 19, from which the water may be drawnout as required for use. Inits assage throu h this circuit the en it isdesired to use the water direct without filtering and under highpressure for example, as 1n case of fire, valves 17 an ressure of t ewater iso viously reduced.

14 are closed and valve 20 is opened and the water then passes directlyfrom the pipe 21 into i e 1 0 and thence out past the valve 20. henit isdesired to removethefilter of impurities which accumulate in the barrel1, valves 17 and 2O are closed and valve 14 and faucet 16 are opened,whereupon the water passes from pi e 21 into pipe 10 throughI ipe 12into tlie barrel 1 near the large endp of the cone' 7 and flowing to theleft-carries with itthe sediment from barrel 1 into reducer 5,\andthence out through faucet-16. In this manner the filter may be veryquickly cleared of the impurities which have accumulated. Access ymayreadily be had to the filter cone at any time by merely unscrewingunions 4 and 13. This ermits the barrel 1 and cone 7 to be wit drawnwithout disturbing any of theother connections, and cone 7 may then beeasily taken out ofthe barrel 1.

What I claim is In a filter, a filtering barrel, an inlet pi e atone'endfthereof, an outlet pipe at tiie other end thereof, unions'connecting the barrel with said inl'et and outlet i es, a fil.
